S3882P
Current Mode PWM Controller
Descriptions
The S3882 is fixed PWM controller for Off-line and DC-DC converter applications.
The internal circuits include UVLO, low start up current circuit, temperature compensated reference, high gain error amplifier, current sensing comparator, and high current totempole output for driving a power
MOSFET.
Also S3882 provide low start up current below 0.
3mA and short shutdown delay Time typical 100nsec.
S3882 have UVLO threshold of 16V(on) and 10V(off).
